After some test runs, the software company Runtriz has released the Hotel Evolution. Check into a place that features them, like the Malibu Beach Inn, and the staff will load the application on your iPhone or iPod touch or lend you a unit for your stay. Your room number is the password. Get your suit dry cleaned, arrange for a wake-up call, order room service, or call for extra shampoo. You can also check on local attractions or set the gadget to “Do Not Disturb.” Runtriz also offers touchscreens for bars and restaurants.
